VANCOUVER, Oct. 18, 2013 /CNW/ - The Company reports that
its field crews have made a discovery (the "Sierra Target") on its
100% owned El Cobre property Sonora,
Mexico. The new Sierra Target consists of hydrothermal
breccias, with diatreme characteristics and occurs in Miocene
volcanic units at an elevation of some 700 meters above, and
further to the West of Westminster's Montoso porphyry system
currently being explored under option by Capstone Mining Corp.
Seventeen hand samples were collected and assayed using various
ore grade methods which determined an average grade of 4.8% copper,
101 g/t silver (400 g/t cutoff) and 4.4 g/t gold. The slabbed
rock samples contained no obvious sulphides but were rich in barium
and iron (hematite ranging from about 3% to 12% Fe). The
accompanying table shows the highest contents of silver assayed
1,479 g/t (47.4 oz/t), gold 21.79 g/t (0.69 oz/t) and copper 10.2%
with these values reported from 3 different samples. These breccias
also appear to be rich in bismuth, mercury and tungsten and
represent a new deposit type for the Company's Sonora properties. See
http://www.westminsterres.com/s/El_Cobre_Property.asp?ReportID=607894
The steeply dipping breccias appear to be in a
fluidized zone where crackle, jigsaw and rock flour cemented matrix
textures are present. The variable nature of the clasts is very
evident as some are green colored with malachite or chrysocolla
while other samples without significant copper oxides also contain
high percentage grades of copper. Two separate exposures about 150
meters apart were likely explored in the 1950s by hand mining for
the high-grade silver in brecciated material.
The company plans to further map and
systematically sample the target area. The previously flown VTEM
and MAGNETIC Surveys have identified conductive and high-low
magnetic patterns which may indicate hydrothermal activity in the
area associated with the breccia hosted mineralization.
Preparation and Analyses
Representative hand samples collected from the
Sierra target breccia were shipped to Canada where they were sawn and slabbed. The
offcut rock portions were numbered and sent for sample preparation
at Acme Laboratories Vancouver. The numbered slabs were kept for
reference and mineralogical investigation. Acme Labs used the
prepared pulps to determine elemental and metal contents by assay
and check analysis including methods 1F06, G814, G613, 7TX, 7TD,
G6Gr, 4AB1, 2X and G1E.
This assay and geochemical characterization of
the high grade Sierra breccias mineralization now has provided the
Company with the best assay methodology to use during its
systematic sampling of the Sierra target area.
